AUTOMATIC GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent N o. 686,307, dated November 12, 1901. Application filed April 1l, 1898. Renewed March 25, 1901. Serial No. 52.823. (No model.)

vTo @ZZ whom t may concern:

Be it known that I, HARRY H. KLAYER, a citizen of the United States, residing at the city of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Automatic Gas-Governors, of which the following is a specification.

The object of my invention is to produce a cheap, simple, and eflcient device for automatically controlling the supply of gas to the pipes which lead to the burners.

The arrangement of the parts and their construction make this device superior to the gas-governors now in use and obviate their defects. When once adjusted, it automatically adapts itself to the varied flow of gas consequent upon the use of varying numbers of gas-burners. Its advantages will readily become apparent from the following speciication and claim and the drawing hereto annexed, in which the figure is a sectional elevation of my automatic gas-governor.

A represents a cup or cone shaped casing or casting, preferably cast in one piece, having an exteriorly-screw-threaded short inletpipe or neck B, through which passes an inlet or opening C, the feed-pipe D being also cast in one piece with casting A. At the top this casing or casting A is so shaped as to forln a hood or annular elevation E, the periphery F of the casting, however, extending up still farther, an annular or circular depression G being thus formed between the hood E and the peripheral wall F. This cupshaped casting forms the gas-supply chamber H. J represents a connection or coupling between the chamber H and the gas-meter. This connection is preferably screwed onto the neck B, its screw-threaded end K fitting the pipe which leads to the gas-meter. This connection is pipe-shaped, at one point, however, bulging out to form an auxiliary gassupply chamber L.

M represents a cap which fits over the casting A at the top, the part-s being finely ground to make a close connection, the cap being firmly held in place by a set-screw N, lying in the housing O, which set-screw impinges against the casting A.

P represents a oat like an inverted cup, being somewhat heavier in the center to form a bearing b. This bearing b and the center opening d through the cup or iioat P are screwthreaded, fitting and working on the screwthread a on the upper end of the valve-stem R. This valve-stem passes through the center of the cup or float P, the cup being adapted to screw up and down on said valve-stem- R. The valve-stem R passes vertically through the gas-chamber H, through hood E, and through the opening C, carrying at its lower end the valve S. The valve-seat for valve S is represented by the letter T. This valve-seat T rests on a shoulder a in the connection .Land whenthis connection is screwed up tightly against the neck B the seat is firmly held in place. At its upper end, beyond the float P, the valve-stem carries the washer d, weights W, and adjusting screwnut Y. When screwed down in place, the washer ts snugly on the float P, allowing no gas to escape. The Weights W are very tightly screwed on or fitted to the valve rod or stem R, so that there will be no vertical or lateral displacement.

Z represents a seal made of mercury or other desirable material. This mercury seal lies in the annular recess G, the edge of the float resting in the mercury, as shown.

The parts are disengaged as follows: The connection J can be unscrewed from casting or gas-chamber H. The valve-seat T is then loosened and hangs loose on the stem R. The set-screw N can be unscrewed and the cap M can be lifted off. Nut Y and weights W can then be runscrewed from the valvestem R and the washer CZ then removed. The valve-stem R can then be pulled out and the valve-seat taken oif. All the parts are now disengaged. It can readily be seen how they can be replaced. At the point where the valve-stem R passes through the hood E aslight space d is left, through which gas passes. The gas passing through the spaces d passes upward till it strikes the oat P. The mercury seal Z keeps the gas from escaping. By reason of the use of auxiliary chamber Land the varying size of connection J, which can be screwed onto casting or chamber H, the governor can be placed on gas-meters or gas systems in which any number of burners are used. Thus itis not necessary to make dierent sizes of governors, as is now the system in vogue.

IOO

governor is ready for its occupation.

The casting A, cap M, cup or oat P, connection J, valve S, seat T, valve-stem R washer d, weights W, and screw-nut Y are made of any desired material and can be made of any shape and their arrangement slightly changed. I

The device operates as follows, to wit: It is first necessary to adjust the governor to the maximum amount of gas to be consumed. For example, if there are twenty gas jets or burners in the system to be governed the full amount ot gas used to burn all the twenty burners is first ascertained. This is done by working the set-screw Y and float P and weight-s W up or down, as the case may require, until the proper adjustment is made.

The proper weight W to properly counteract or equalize the pressure exerted by the incoming gas must also be ascertained, and when this adjustment is properly ascertained the The gas from the meter passes, as indicated by the arrow, through 'into the auxiliary reservoir L, filling thereservoir. It then tiows upward between the valve S and valve-seat T, as indicated by arrows, passing through the passage C into the reservoir H, this reservoir H becoming thoroughly charged with gas. At this stage theln'atural tendency would be from the pressure against the valve S to rise up against its seat T, and consequently stop the further flow ot' gas into the reservoir H; but by means of weights W, which cause a downward pressure on cap or float P, which in turn controls valve S, (which weights have been gaged by the tested pressure of the How of gas against valve S, as before stated,) the said valve S remains in its normal position and the passage between Valve S and its seat T is kept open, (great or small, as it may be from the previous first adjustment.) Now when the gas is being consumed by the burners attached to pipes supplied by pipe D the gas or charge in reservoir H becomes diminished, thus allowing or causing the float P to fall, which in turn, controlling the valve S, removes the said valve farther from its valve-seat T, enlarging the inlet between the valve and seat, allowing a further supply of gas from the meter. Hence when the automatic action of the governor asserts itself the less the consumption of gas through the pipe D to the burners the less the downward pressure on iloat P by the weights W. Hence the smaller the vent between the valve and valve seat consequently the less the amount of gas admitted to reservoir H, and, vice versa, the lnore the consumption of gas through pipe D the greater the downward pressure on oat P bythe weights W. Hence the larger the vent between the valve and Valve seat consequently the greater the amount of gas admitted to reservoir H, thus demonstrating the perfect automatic action of the supply of gas to reservoir H, thus equalizing the consumption from reservoir H. This automatic action saves gas and allows only that gas to escape which can be naturally consumed by combustion.

The fact that the governor is absolutely automatic, that only one size governor-can be used for varyin g burners and gas systems,and the fact that the weights for regulating the float are rigidly attached to the valve-stem, allowing no vertical or lateral displacement, are the salient points and advantages of my invention.

What I claim as new and of my invention, and desire to secure by Letters Patent, is

ln an automatic gas-governor, the hereindescribed casting, being a cup-shaped body forming a hood at the top,the lower part being hemispherical in shape, having an inlet directly beneath and in line with the valve and an outlet at right angles thereto, the whole being cast in one piece, the hood at the top being provided with an annular recess for holding the sealing fluid, this hood being the top of the gas-receiving chamber,an inverted, cup-shaped float made of one piece, said float being thickened at the center and being mounted on and working up and down for adjustment on a valve-stem, and situated directly above the hood of the casting and lying in juxtaposition therewith; said float moving up and down in the sealing fluid; weights attached to the valve-stem above the float to adjust the iioat to varying pressures of different gas-meters; the valve-stem secured to the float and extending vertically through the oat, hood and gas-supply chamber formed by the casting and down into the inlet-passage; a valve connected to the lower end of the valvestem,said valve-stem workingloosely through the said hood, a non-elastic valve-seat held in place by the coupling at the lower end, said coupling beingscrewed upon the screw-thread at the lower end of the cup-shaped casting,the valve being situated directly in the inlet-passage so as to receive the direct action of the gas, a washer and screw-nut lying and working up and down on the valve-stem above the tioat to adjust and regulate the adjustmentweight lying directly upon the float; an auxiliary chamber below the regular gas-chamber and a cap secured over the said casting at the top, all combined and operating as set forth.
